Alternative usage of PHP return statement is not only in functions

Share another function of PHP return statement and a wonderful use method seen in bbPress code.

1 Think that return can only appear in functions until you look at the code for bbPress:

<?php
require_once('./bb-load.php');

bb_repermalink(); // The magic happens here.

if ( $self ) {
if ( strpos($self, '.php') !== false ) {
require($self);
} else {
require( BB_PATH . 'profile-base.php' );
} // www.ofstack.com
return;
}

Can return still appear outside the function? This is unimaginable in C language.

Check the PHP manual under 1: If you call the return statement in 1 function, it will immediately end the execution of this function and return its parameters as the value of the function. If called in global scope, the current script file stops running.
